Title:
POSITIONING CONTROL DEVICE AND MOLD-CLAMPING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/217222
Kind Code:
A1
Abstract:
The present invention is a positioning control device which is for positioning a moving body in a target position and is installed in an industrial machine equipped with a driving unit with a motor, a moving body that can be moved by the driving unit, a first detection unit for detecting the position of the moving body on the basis of the amount of driving of the driving unit, a servo amp for executing a first feedback control for feedback-controlling the driving of the motor on the basis of first detected values from the first detection unit, and a second detection unit for detecting the position of the moving body when the moving body has come within a certain distance of the target position. The positioning control device is provided with a controller for controlling the servo amp. The controller has a switching unit for switching the control mode between a first control mode for executing the first feedback control, and a second control mode for executing a second feedback control in which the first feedback control is nullified and the driving of the motor is feedback-controlled on the basis of second detected values from the second detection unit.
